So I stand under correction but I'm pretty sure it's closed but not due to fires - I don't think they hit there. Rather due to TMNP issues again - they need to do an official environmental management plan (the last one was not recognised apparently). Some of Red hill is also apparently private land. Right before it closed (or rather before everyone realised it was closed) the crime was frequent and pretty bad.

I think about 90% of what I say is true, but I may be fuzzy on some stuff. But in short if you go, you should probably be prepared to be mugged and fined. Sadly.
